Fuel contamination of the oil is caused by unburnt fuel passing the piston rings on the compression stroke just before ignition. The effects are increased on new age thumpers because often manufacturers will use one less ring than conventional 4T's & these things rev so much higher.
This is why you shoud change your oil more frequently. The fuel breaks down the oil.
